            Status: NEW
         Component: WebSite
           Product: Zanata

Description of problem:
When an uncaught exception happens in client side (browser), it's not obvious
to user. From troubleshooting perspective, at the moment we only log the
exception in console which can only be seen by using Chrome or Firefox addon. 

Version-Release number of selected component (if applicable):
1.7 and below

How reproducible:
Always

Steps to Reproduce:
Known bugs are all fixed so this may need to be created on purpose.

Actual results:
Exception stacktrace is shown in Chrome console. User only sees a javascript
error.

Expected results:
Exception and error is shown on screen so that user is aware there is an error
so that they can cease work and report the error to Zanata dev team.

Additional info:
Probably helpful to also include zanata-dev mailing list address or bugzillar
link in the display to facilitate communication.
